Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand for gripping an IC, and more particularly to a hand for an automatic machine for inserting an IC into a socket and removing the IC from the socket.

[0002]

2. Description of the Related Art A conventional IC insertion / extraction hand of this type includes an insertion / extraction mechanism that operates in a vertical direction and a gripping mechanism that grips an IC.

[0003]

In the above-described conventional hand for inserting and removing an IC, since a stopper is not attached to the gripping mechanism, the hand-held printed circuit board to which the socket is attached has a warp or a difference in board thickness, and the hand has a problem. The relative position of the height of the socket and the IC and the relative position of the height of the IC and the hand pawl vary due to the adjustment of the height of the IC and the board. There was a drawback of making a mistake.

[0004]

According to the present invention, there is provided an IC insertion / removal hand, which comprises an insertion / extraction mechanism operable in a vertical direction, and a stopper which contacts with an upper surface of a socket in which the IC is to be inserted / extracted in conjunction with a lowering operation of the insertion / extraction mechanism. And a gripping mechanism that grips the IC while maintaining the height at which the stopper portion is in contact with the socket, and inserts and removes the IC from the socket in conjunction with the insertion and extraction mechanism. Further, the insertion / extraction mechanism may include a linear motion actuator, and the gripping mechanism may include an opening / closing mechanism that allows the IC to be gripped freely and a pusher that inserts the IC into the socket.

[0005]

Next, the present invention will be described with reference to the drawings. FIG. 1 is a side view of an IC insertion / extraction hand according to one embodiment of the present invention.

In this embodiment, the insertion / extraction mechanism 1 has a linear motion actuator 11 which operates in the vertical direction. A gripping mechanism 2 that grips the IC 3 and inserts into and removes from the socket 4 opens and closes the pawl 22 and operates the linear motion actuator 1.
1, a pawl 22 for directly gripping the IC 3, and a pusher 23 fixed to the chuck 21 for inserting the IC 3 into the socket 4. The stopper portion 5 is movably attached to the gripping mechanism 3 and contacts the socket 4 with the actuator 11 lowered. I
The socket 4 to which C3 is inserted and withdrawn is attached to the board 41. In this embodiment, IC3 is particularly ZI
It is a P (zigzag in-line package) type IC.

The operation of this embodiment having the above-described configuration will be described below. When the IC 3 is inserted, the insertion / extraction mechanism 1 is lowered until the stopper portion 5 comes into contact with the socket 4, and the pawl 22 is opened in that state, and the IC 3 is
Is inserted into the socket 4, the insertion / extraction mechanism 1 moves up.
According to this method, the IC 3 can be inserted into the socket 4 without variation in the relative position of each socket 4 and the IC 3 in the height direction.

When removing the IC 3, the insertion / extraction mechanism 1 is lowered with the pawl 22 open, the pawl 22 is closed with the stopper 5 in contact with the socket 4, the IC 3 is gripped, and then the insertion / extraction mechanism 1 is raised. Then, the IC 3 is removed from the socket 4. Thereby, the IC 3 can be gripped and removed without the relative position between the pawl 22 and the IC 3 being shifted.

[0009]

As described above, according to the present invention, the stopper is provided in the gripping mechanism, and the height of the hand is determined based on the height of the socket when inserting and removing the IC. This has the effect of suppressing the occurrence of displacement between the position and the relative position of the IC and the hand pawl, and preventing lead bending and gripping errors.
